I have been having this feeling like I am going to crash and my car is going too fast. Also feel like my mind is going none stop, I feel like the world is speeding around me and im moving too slow. Also feel jittery if I sit in one spot for too long. Also I don't feel as tired now at night and I keep waking up at 4:30 and it drives me crazy that I cant sleep without a sleeping pill. Whats going on with me, is it bipolar related?
